A very singular and most distinct species, two feet and more high, branched. Leaves principally from the 
base, but by no means all radical, thick and fleshy, of three deep obcordate and lobed segments. Flowers 
in large lax panicles, of a red-purple colour, with a very long spur, nearly glabrous. Petals all spathulate ; 
the upper ones longer than the calyx, much exserted. The Z>. nudicaule of Torrey and Gray, though 
found by Mr Douglas, does not quite accord with this plant, and these authors do not notice the singularly 
fleshy leaves.

My specimen of this plant shows that the flowers are sometimes in rather large lax panicles. Some of the 
leaflets are more than two inches in diameter. 
Ord. III. PAPAVERACE^. Juss. 
The plants of this family in Mr Douglas’ collection are possessed of peculiar interest ; affording, as they 
do, eight new species, and three new genera ; of which latter, one is remarkable for the beauty of its blossoms, 
as another is for its frulescent habit and rigid coriaceous leaves and fruit, an anomaly in the Order. Some 
of these having been cultivated in the garden of the Horticultural Society, our valued friend Mr Bentham 
has directed his attention to them, and has admirably characterized the new genera and species above alluded 
to, in the Transactions of the Horticultural. Society of London. His characters we cannot do better than 
adopt.

“ This little annual,” Mr Bentham observes, '* flowered ” (the first season) “ very sparingly ; but the fine 
specimens transmitted by Mr Douglas in a dry state, promise that it may become as interesting to the horti- 
* There is a very distinct species of Berberis (Section Mahonia), in Mr Andrieux’s collection of “ Plantce Mexi- 
cans exsicc. n. 469,” without any name, and with only the remark, “ Locus proprius incertus.” It may be thus 
characterized : —
